The friendly rasp of ChatGPT’s ‘Sky’ voice is getting the AI company into hot water. Last week, OpenAI launched ChatGPT 4o, a new model of its chatbot assistant that converses in almost real time. Users could choose from five voices, including Sky, whose friendly intonation had a slight rasp vaguely reminiscent of Scarlett Johansson—an actor who, not coincidentally, had voiced an AI assistant in Her, a 2013 film that follows a man who falls in love with his computer’s operating system.
